Japan Airlines will become the fourth airline in a year to use biofuel during a test flight tomorrow.

The hour-long Boeing 747-300 flight will be powered by 50 per cent traditional jet fuel while the other half came from a biofuel blend. Biofuel used in the latest flight at Tokyo airport was a mixture of camelina (a kind of flax), the flower jatropha and algae.

The world’s first test flight using biofuel was conducted by Britain’s Virgin Atlantic Airways last February.
